How do you know if a value is a solution for an inequality? When you replace the value for the variable in the inequality and then solve the problem. If the answer is a true statement, then the value was an element of the solution set. If the answer is false, the value is not an element of the solution set. How is this different from determining if a value is a solution to an equation? Solutions to equations will be exact. Solutions to inequalities will part of a solution set. If you replace the equal sign of an equation with an inequality sign, is there

Unformatted text preview: ever a time when the same value will be a solution to both the equation and the inequality? Yes, when the inequality has a less than or equal to sign, or a greater than or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality; whereas the solution for the equation will be an exact answer. Write an inequality and provide a value that may or may not be a solution to the inequality. A: 3x - 4 > 11 x = -2...
